Sphynx digestive system question

Hi.. this is my second post here just wanting to learn more about the breed since i have had a sphynx before. On August 2017 is when i had gotten my first baby boy king. Me & my boyfriend went through hard times with our first baby and was really heartbreaking for the both of us. & really really expensive bills.. We ended up giving king up to a specialist. Now we have gotten another litte baby boy that we named tommy. He is almost soon to be 3months. No shots yet till the end of the month he will get his first shots.. He has only gotten dewormed.. since he started eating dry food i have been giving him pumpkin mixed with his dry kitten food.. No diharrea just soft formed stools, but lately i have been noticing bloody stools. Im not trying to worry but i am getting a bit worried because i have been through this same path before and its depressing and its just sad I really hope is nothing bad.. any suggestions on what i should do? Or what does this mean? My sister has both parents & i have tommys other 3 siblings with him till they are ready to head to their homes.. they are all so playful and eat good and all have soft formed stools.. theres has been one time i have had cleaned their litter box and saw a bloody stool this was like two three weeks ago, and now today.. and when i saw tommy using the litter box today I actually saw him finish up in his litter box and there was bloody stool.
